Implement a menu when you right-click on songs in the SongBrowser.

[brokenprogrammer]

When right-clicking a song in the SongBrowser a new menu with the following options should be displayed:

• Play
• Add to queue
• Add to playlist -> With submenu of all playlists (Playlists is not yet implemented so just a button)
• Share -> With submenu that we can add buttons to later on.

Functionality for the individual buttons do not have to be implemented, we just want the actual menu for now.

The JavafX term of the type of menu that will pop up is "Context Menu". Oracle JavaFX Menu Tutorial ContextMenu Javadoc
